SPECIFICATION forming part of Letters Patent No. 772,662, dated October18, 1904.

Application filed May 25, 1903.

To all whom it may concern.-

Be it known that I, ELWYN A. MALLoRY, a citizen of the United States,residing at Canton, in the county of Stark and State of Ohio, have invented certain new and useful Improve men ts in Metal Studs; and I dohereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the annexed drawings,making a part of this specification, and to the figures of referencem'arlred thereon, in which Figure 1 is a perspective view showing twostuds connected together to produce ahollow wall or partition. Fig. 2 isa transverse section through line X X, Fig. 1. Fig. 3 is a view showingthe one member of the stud and a portion of one of theconnecting-plates.

,Fig. 4 is a view showing a single stud.

The present invention has relation to metal studs designed to take theplace of ordinary wood studding and also to hold in proper positionsuitable metal lath or sheets for receiving and holding the plaster. Thelath or plaster-holding sheets form no particular part of the presentinvention and may be of any suitable construction, but should be ofmetal, so as to produce when the different parts are properly assembledand the plaster applied a fireproof structure.

Similar numerals of reference indicate corresponding parts in all thefigures of the drawmgs.

In the accompanying drawings, 1 represents the studs proper, which areformed of any desired length, and when ahollow wall or partition is tobe constructed the studs are held in proper parallelism by means of theconnecting-bars 2, which connecting-bars are formed of a length tocorrespond with the distance between the inner edges of the parallelstuds.

For the purpose of holding the studs in proper relation one with theother the bars 2 are provided with the divided tangs 3, which dividedtangs are bent around the studs, substantially as illustrated in Figs.1, 2, and 3, and their out r ends bent or hooked over the outer faces ofthe studs.

The outer {any of the studs 1 are prefer- Serial Nu. 158,618. [Nomodel.)

ably grooved; but the form of the groove may be varied without departingfrom the nature of my invention, or in some instances the outer face maybe straight.

The studs are each formed of asingle piece of metal bent intosubstantially rectangular form, and the edges of the studs upon theopposite side from that to which the plasterholding lath or sheets areto be attached are open, or preferably so, the object being to savematerial and also to allow cement to be placed between the flanges ofthe studs, ii dc sired.

The lath-attaching edges of the studs are provided with a series ofslots 4, which slots are cut through the material or punched and thesevered edges of the slots 4 bent inward, as illustrated in Fig. 2, withthe edges in close proximity to each other, so that they will bind thestaples 5, which staples are for the purpose of holding the lath orsheets, as the case may be.

It will be understood that as the staples 5 or their equivalents aredriven into the slots the edges of the slots will impinge the staplesand securely hold them in proper position.

It will be understood by my peculiar arrangement I am enabled to producea stud for building purposes that will be light and inexpensive and welladapted for the purpose designed.

I do not desire to be confined to any particular shape of thecross-section, as the only object is to provide a metal stud to whichstaples or their equivalents may be attached and held in properposition.

By providinga series of slots and spacing them from each other i. amenabled to provide means for properly connecting the lath orplaster-holding device without weakening the stud, and at the same timethe slots being comparatively short they will not open, so as to causethe staples to become loose, and that each staple has its individualslot, so that there is no danger of loosening the staples already drivenby driving an additional number of staples.

In the drawings I have illustrated the edges of the studs provided withthe slots inclined toward each other, by which arrangement the slots maybe located at the apex of the grooves thus formed, and thereby form to acertain extent guide-surfaces to direct the points of the staples ortheir equivalents to the slots 4.

The studs proper may be formed of any desired length, and in case longstuds are required sections may be connected together by riveting orotherwise; but when so connected together they are to constitute acontinuous stud throughout its entire length regardless of the number ofsections.

Having fully described my invention, what 1 claim as new, and desire tosecure by Letters Patent, isl 1. As an improved article of manufacture,a metal stud, the outer face thereof provided with a groove, a series ofslots formed in the apex' otthe groove, the edges of said slots extendedtoward the inner edge of the stud, substantially as and for the purposespecified.

2. The combination of two parallel studs, each provided with groovesupon their outer faces,slots formed in the apexes of the grooves, barsprovided with divided tangs and the tangs adapted to be bent around thefaces of the studs and into the grooved faces, and staples adapted to belocated through the slots, substantially as and for the purposespecified.

In testimony that Iclaim the above 1 have hereunto subscribed my name inthe presence of two witnesses.
